What is a common result of ascending too rapidly while diving?

Ascending too rapidly while diving can lead to lung overexpansion injuries, which occur due to the expansion of air in the lungs as pressure decreases during ascent. When divers breathe compressed air at depth, the air in their lungs is under high pressure. If a diver ascends too quickly, the pressure on the air in their lungs decreases very rapidly, causing the air to expand. This expansion can result in damage to the lung tissue and even rupture, leading to serious medical conditions such as arterial gas embolism.

This injury is particularly dangerous because it can result in air bubbles entering the bloodstream, which can obstruct blood vessels and cause critical health issues. Therefore, it is crucial for divers to ascend slowly and safely, following the recommended ascent rates and incorporating safety stops to allow excess nitrogen to be safely released from their bodies.

The other options do not accurately describe the consequences of rapid ascent. Feeling light-headed may occur, but it is generally not as severe or directly related to the dangers of rapid ascent as lung overexpansion injuries. Improved oxygen absorption and enhanced diving experience are also incorrect, as rapid ascent can actually detract from the overall safety and enjoyment of a dive.
